Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lever-type connector of a type directly mounted on a board.

[0002]

[Prior art]

 In general, a board-mounted connector has a number of terminals that extend laterally from the rear surface of the connector housing and the middle part is bent toward the board, and these terminals are soldered to the board and mounted on the board. Fixed. The circuit board on which such a connector is mounted is housed in a case for protecting the board, and only the coupling opening on the front surface of the connector is exposed from the side surface of the case.

[0003]

[Problems to be solved by the device]

 However, as shown in FIG. 9, in the lever-type board-mounted connector in which the lever is used to connect and disconnect the connector, the opening 3 is formed in the case 2 for the turning operation of the lever 1. There is a need. That is, since the lever 1 is provided in the connector housing 5 attached to the circuit board 4 so as to be rotatable about the pivot 1a in the direction of the arrow, the case 2 allows the lever 1 to rotate. Therefore, a considerably large opening 3 is required.

However, when the opening 3 is provided in this manner, especially when the lever 1 before connecting the connector is in an upright state, the terminal 6 group extending from the rear surface of the connector housing 5 is provided. It will be exposed through the opening 3. For this reason, there is a problem that the foreign matter that has entered through the opening 3 comes into contact with the group of terminals 6 and deforms them, or electrically shorts them.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a terminal group even if the terminal group is exposed by an opening provided for the purpose of lever operation. There is a lever-type connector that can be protected.

[0006]

[Means for Solving the Problems]

 In the lever type connector of the present invention, a terminal group extending from a connector housing provided with a lever is soldered to a board and mounted on the board, and the terminal group is at least connected to the connector housing. The present invention is characterized in that a terminal cover is provided to cover the board from above (claim 1).

Further, the terminal cover may be integrally provided with a terminal aligning plate having a terminal insertion hole into which each terminal extended from the connector housing is inserted (claim 2).

[0008]

[Action]

 According to the first aspect of the present invention, the terminal group extending from the connector housing is covered with the terminal cover from above the board. Even if there is a need to form an opening in the cover, foreign matter can be prevented from entering the terminals.

Further, according to the invention of claim 2, since the terminal cover is integrally provided with the terminal aligning plate, by inserting each terminal into the terminal inserting hole of the terminal aligning plate, the terminal is arranged. In addition to group protection, the group of terminals can be aligned.

[0010]

[Effect of device]

 As described above, according to the lever-type connector of the present invention, the terminal cover can prevent foreign matter from entering the terminal group and can reliably protect the terminal group. Further, if the terminal aligning plate is also provided, the arrangement of the terminal groups can be aligned to facilitate the work of mounting the connector on the substrate.

The locking claws 37 are rotated by rotating the lid 32. The lid 32 can be maintained in the closed state by engaging with the locking protrusion 38. In the closed state of the lid portion 32, the lid portion 32 covers the terminals 22 from above the substrate 11.

According to this embodiment having the above-described configuration, the group of terminals 22 extending to the rear of the male connector housing 20 is covered with the terminal cover 30 from the upper side, the side, and the rear. Therefore, even if the opening 13 for the turning operation of the lever 21 is formed to be relatively large in the case 12, the terminal 22 group is not exposed, and if the opening 13 is passed through the opening 13. Even if foreign matter enters, it can be reliably prevented from deforming or short-circuiting the terminal group 22.

Further, the terminal cover 30 is integrally formed with the terminal alignment plate 34 having the terminal insertion holes 33. By inserting the terminals 22 into the terminal insertion holes 33, the arrangement of the terminals 22 can be properly aligned. The condition can be corrected. As a result, the mounting work of the connector housing 20 can be efficiently performed.
